public void flip(int fromIndex, int toIndex)

Example

In the following code shows how to use BitSet.flip(int fromIndex, int toIndex) method.

/*  ww  w.ja va 2 s  .c o  m*/
import java.util.*;

public class Main {

   public static void main(String[] args) {

      
      BitSet bitset1 = new BitSet(8);
      BitSet bitset2 = new BitSet(8);

      // assign values to bitset1
      bitset1.set(0);
      bitset1.set(1);
      bitset1.set(2);

      // assign values to bitset2
      bitset2.set(2);
      bitset2.set(4);

      // print the sets
      System.out.println("Bitset1:" + bitset1);
      System.out.println("Bitset2:" + bitset2);

      // flip from index 2 to index 5 of bitset1 and print it
      bitset1.flip(2,5);
      System.out.println(bitset1);
      
      // flip from index 1 to index 5 of bitset2 and print it
      bitset2.flip(1,5);
      System.out.println(bitset2);

   }
}

The code above generates the following result.
